
In an expanded system (TSP- Link), this attribute is used to read or write to the
system4 node registers.

Reading a system4 node register returns a numeric value whose binary equivalent
indicates which register bits are set. The bits of the system4 node register are
identified as follows:
B0-EXT bit B4-Node 46
B1-Node43 B5-Node47
B2-Node44 B6-Node48
B3-Node45 B7-Node49

For example, assume value 9 is returned for the enable register. The binary
equivalent is 0000000000001001. This value indicates that bit 0 (EXT) and bit 3
(Node 45) are set.

Assigning a value to the status.system4.enable attribute sets the extension bit or a
node bit of the system4 node enable register.
